DOOR OPENER AND CLOSER.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed SeptemherIZZ, 1906. Serial No- 335,752-

To (DZ/Z whom, it may concern:

Be it known that I, DANIEL WILDE, a citizen of the United States, residing at Washing ton, in the county of WVashington and State door openers and closers, the object being tov provide a simple means for opening or closing a door situated at the foot of a stair-case, from an upper landing or at some other remote point, and a further object is to provide means forsecuring the door in a closed, open or intermediate position.

Another object of my invention is to provide means whereby the door can be unlocked at the same time the door is opened, or in other words, when it is desired to open the door, the means for opening or closing the door are so connected with the locking means that the lock will be operated at the same time the door is opened or closed.

WVith these objects in view, my invention consists of a drum or wheel which can be placed at the head of the stairs, or if the door is to be operated on the same floor, at any place desired, and by which the door is opened and closed, it is also provided with means for holding the door in locked position so that a person attempting to enter the building could not enter until the means which holds the drum is released. This drum by the use of this means can hold the door in any position the operator wishes.

My invention further consists in certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in perspective, showing the door in its closed position with my improved opening and closing mechanism. Fig. 2 is a view in side elevation of the locking means and drum, with the cap removed. Fig. 3 is a view of the guide-way. Fig. 4 is a view of the slide. Figs. 5 and 6 are details.

- A, represents a guide-track, adapted to be secured along the wall from the door 1, at i the inclination of the stairs. This track extendsto the height desired, and is then covered by a cover 2, which cover extends to the cap 3, of the drum or wheel 4, at the head of the stairs. This guide track may be variously constructed; for instance, it may be cast or made of sheet metal bent into shape with the overlapping flanges 5, 5, projecting inwardly from its outer face.

A plate B, is secured to the wall in any suitable manner, and the drum or wheel 4 is loosely mounted on the hub 7 of the plate.

.The drum or wheel may be constructed in any suitable manner, but I have provided on its lower face, teeth 8, 8, which are adapted to engage dogs 9 and 10, which will be presently described. On the upper face of the drum a handle 14 is secured whereby the drum may be revolved.

Dogs 9 and 10 are pivotally secured to the plate and are thrown in and out of engagement with the teeth of the drum by the cam levers 1 1, 11, which are loosely secured to the plate by studs 12, 12. The dogs are held in engagement with the teeth by the spring E, which is looped at its center and a screw 13 passes therethrough and into the plate B.

The cap 3, is placed over the drum and plate, and is provided with an opening 15 for the handle 14, and on each side openings are formed for the cam levers 11, 11.

Connected to the drum-4 is a cable 17, preferably of wire, which passes down the track A, to a runner 19, to which it is connected, by the plate 18 at a, and then passes around a pulley 20 at the lower end of track, and then through an opening formed at b, in the opposite side of the runner and then back to the drum 3. The plate 18 is held against the base of the runner 19 by a screw 18, thereby making a binding connection with the cable.

At the rear side of the door, and preferably below the alinement of the knob, a plate D is secured by screws or other means passing through slots 23. This plate is struck up on its sides and bent forward as at 24, thereby forming a guide-way, and the ends 25 are bent downwardly and soldered or secured to the base of the guide-way, to form stops for the slide O, which is adapted to slide therein. The slide is provided with a staple like projection 26, to which is connected a rod 30 which connects the slide to the runner 19.

Secured to the door knob shank is an arm 27, provided with an opening for the screw 28, which forms a rigid connection between the shank and arm. Secured to the arm is a wire or rope 29 which connects it to the slide O. This arm is connected, preferably, to the door lock commonly in use, which permits one of the knobs to unlock the door at any time, and the other knob to be so fixed that after the lock has been thrown, it will not permit the knob to turn.

The operation is as follows: Supposing the door to be closed, and it is desired to open it from the head of the stairs, if the dogs 9 and 10 are in engagement with the teeth 8 of the drum or wheel 4, the dog 10 is thrown out of engagement with the teeth by the lever 11, and by turning the handle 14 the cable 17 is wound around the drum which draws the runner 19 along the track A, which pulls the slide C by the rod 25, rearwardly, and at the same time the arm 27 which connects the knob with the slide will turn the knob, whereby the door is released and can be opened' The handle can be revolved until the door is entirely opened, or the door may be opened to any desired distance, and as the dog is in contact with the teeth the door cannot be closed until the do is released from engagement. If desired, 0th dogs can be thrown out of engagement while the door is being opened, and then the dog 9 can be thrown.

into contact. If a person desires to go out, the door can be opened from the top of the stairs by the operation above described, without either dog being in contact with the teeth, and after the door is opened, the dog 10 can be thrown into engagement with the teeth and as the door is closed by the person going out the door will become locked, and no one can enter, until the dog is thrown out of engagement with the teeth 8 of the drum.

It will be seen that when the dogs are out of engagement with the teeth of the drum, the drum is free to revolve by means of the handle or by the opening or closing of the door, but when both dogs are in engagement with the teeth of the wheel or drum the door can not be opened or closed.

From the foregoing it will be seen that I have provided means by which a door can be unlocked and opened in a single operation, and closed at the will of the operator.

It is evident that many slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention,

and hence I do not wish to limit myself to the exact construction herein set forth, but

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A door opener and closer comprising a track, a runner fitted to slide therein, a rod connected with the runner and door, an endless rope or cable secured to the runner, and a drum connected with the rope or cable for opening and closing the door.

2. A door opener and closer comprising a track, a runner fitted to slide within the track, a cable secured to the runner, means connecting the runner and door and means for fastening'the cable for securing the door in an open, closed, or intermediate position.

3. A door opener and closer comprising a track, a runner adapted to slide in the track, a cable secured to the runner, a rod connected to the runner and door, a drum or wheel, said cable secured to the drum, and means for .rotating the drum to open or close the door.

4. The combination of a door opener and closer, a track, a runner adapted to slide therein, an endless cable secured to the runner, of a slide, a rod connected to the runner and slide, and means for operating the slide whereby the door can be opened.

5. The combination of a door opener and closer, a track, a runner adapted to slide therein, a cable secured to the runner, means connecting the door and runner, of a drum or wheel, said cable connected to the drum, dogs engaging the drum, and means for ro tating the drum whereby the door can be opened or closed.

6. The combination of a door opener and closer, a track, a runner adapted to slide therein, of a slide, a door knob, means for connecting the knob and slide, and means connected to the slide and runner whereby the knob is operated and the door opened or closed.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

DANIEL WILDE.
